Tankless Water Heater Replacement FAQ

• What are the clearest signs that my tankless water heater needs replacement?

  The clearest signs are consistent failure to heat water, error codes that do not clear after a reset, water leaks from the unit, or if the cost of a single repair is more than 50% of the cost of a new unit. If your unit is over 20 years old, replacement is also strongly recommended.

• How long does a tankless water heater replacement take?

  A standard tankless-to-tankless replacement typically takes 4 to 6 hours. This is faster than a tank-to-tankless conversion because the necessary venting and utility lines are already in place.

• Should I replace my old tankless unit with a newer, more efficient model?

  Yes. Newer tankless models often feature higher energy efficiency ratings (EF) and better flow rates. Replacing an older unit with a modern one can significantly reduce your energy consumption and provide a more reliable hot water supply.

• Is it necessary to replace the venting system when replacing a tankless unit?

  In many cases, yes. While the new unit may use the same vent location, modern tankless heaters often require specific venting materials and diameters to meet current safety and efficiency codes. Our technicians ensure the venting is compliant with the new unit’s specifications.

• What is the lifespan of a new tankless water heater?

  With proper Tankless Water Heater Maintenance (specifically annual descaling), a high-quality tankless water heater can last 20 years or more, which is significantly longer than the 10-15 year lifespan of a traditional tank unit.
